[0022] The specific operation is as follows: the servo motor 8 drives the screw 9 to rotate, so that the screw nut 10 drives the connecting plate 11 and the ventilation net 12 to move horizontally along the outside of the screw 9. At the same time, the spring 13 generates elastic force for resetting, changing the support angle of the support rod 14 to the fixed block 15, causing the brush plate 16 to move longitudinally on the surface of the ventilation net 12, brushing off the dust remaining on the ventilation net 12, so that the ventilation net 12 is always maintained in a state of high-efficiency ventilation and filtration.

[0023] like Figure 2As shown, a heat dissipation component 4 is arranged on the upper left side of the rear end of the box body 1, and the heat dissipation component 4 includes a forward and reverse motor 1 401 and a drive shaft 402, the output end of the forward and reverse motor 1 401 passes through the rear end of the box body 1 and is connected to the drive shaft 402, the heat dissipation component 4 also includes a movable plate 403, a forward and reverse motor 2 404 and a fan blade 405, and a movable plate 403 is arranged on the outside of the drive shaft 402, the forward and reverse motor 2 404 is installed on the top of the movable plate 403, and the output shaft of the forward and reverse motor 2 404 passes through the movable plate 403 and is connected to the fan blade 405.

[0024] The specific operation is as follows: when the movable plate 403 is placed horizontally, the forward and reverse motor 404 drives the fan blade 405 to reverse, absorbing the heat generated by the temperature controller 7 to the height of the ventilation hole, so as to release it to the outside atmosphere through the ventilation hole, thereby avoiding the temperature in the box 1 being too high and causing the life of the temperature controller 7 to be shortened.

[0025] In summary, when the temperature control box for metal surface heat treatment is used, the box door 2 is first opened, and the temperature controller 7 is fixed to the horizontal frame 5 by using existing threaded fasteners. When the multiple groups of temperature controllers 7 are running and generating heat, the fan blades 405 are driven to reverse by the forward and reverse motor 2 404, so as to absorb the heat generated by the temperature controller 7 to the height of the ventilation hole, so as to promote the release of hot air to the outside atmosphere;

[0026] The ventilation net 12 is used to prevent dust and impurities from entering the box body 1. When the ventilation net 12 is blocked, the forward and reverse motor 401 is started to drive the driving shaft 402 and the movable plate 403 to rotate 90 degrees in the clockwise direction, so that the movable plate 403 is placed vertically;

[0027] Then, the servo motor 8 is controlled to drive the screw 9 to rotate, and the connecting plate 11 and the ventilation net 12 are driven to move horizontally along the outside of the screw 9 through the screw nut 10, and the angle of the support rod 14 is changed under the elastic support provided by the spring 13, that is, the fixed block 15 drives the brush plate 16 to move longitudinally on the surface of the ventilation net 12, and the dust remaining on the ventilation net 12 is brushed off by the friction between the brush plate 16 and the ventilation net 12. At the same time, the forward and reverse motor 404 drives the fan blade 405 to rotate forward to blow away the dust, so that the cleaning process of the ventilation net 12 is quick and labor-saving;

[0028] The first forward and reverse motor 401 , the second forward and reverse motor 404 , and the servo motor 8 are all arranged outside the box body 1 to avoid increasing the high temperature inside the box body 1 .
